SI Verdict ⭐ 4.9/5 ⭐ 4.8/5 ⭐4.7/5 ⭐ 4.6/5
  • Kalshi is our number one overall prediction market app for U.S. traders, offering strong coverage across sports and real-world events, streamlined traditional banking options, a user-friendly same-game parlay builder, and performance that mirrors the top mobile sports betting apps. 
  • However, the Polymarket app offers the best overall liquidity and the largest selection of real-world event contracts for trading niche sports, politics, and culture markets. It also allows combo trades with up to 32 legs.
  • The ProphetX app also stands out for its sportsbook-inspired mobile exchange, featuring standout graphics, 0% fees on profitable parlays, and easy-to-read bet slips that use American odds.

What's changed in August 2026

Aug. 10, 2026: We completed a full review of Novig prediction markets and moved them to #4 on our rankings. This coincided with an updated welcome offer and their receiving CFTC approval as a Designated Contract Market (DCM) and a federally regulated prediction-market app.

Aug. 6, 2026: Updated OG.com's review to note the OG combo builder now supports up to eight legs, same-game parlay/combo trades, and eligible player props

Aug. 4, 2026: Removed WA from the list of states where Kalshi is legal to use after state courts ruled that its prediction market platform violates state anti-gambling and consumer protection laws despite its federal CFTC regulation.  
July 2026 updates:

July 23, 2026: We updated the welcome bonuses for Polymarket and Kalshi to the current offers.

July 20, 2026: NFL futures markets added to ProphetX. Market Variety rating boosted to reflect the addition.

July 14, 2026: The combo builder feature was added to the Polymarket app review. Polymarket advertises up to 32 leg combos for their recent promotion, the 'Polymarket Combo Cup'.

July 12, 2026:
We reviewed the new Kalshi Advanced Trading Terminal, a new professional desktop platform.
Title Icon SI Expert Analysis

Kalshi edges out Polymarket for me as the top prediction market app, partly because of its welcome offer, which provides much higher upside.

Both apps are highly polished and widely available, but Kalshi's also proved to be the cleaner, less overwhelming experience for me. Kalshi featured easy-to-read trading slips and a combo builder that had the most extensive player prop markets, which made the transition from betting to mobile trading a better overall experience.

  - Geoff UlrichPrediction Markets Analyst

1. Kalshi - Best overall prediction market app

🏆 SI Verdict: ⭐4.9/5
The Kalshi prediction market app takes the top spot because it delivers the most balanced experience across liquidity, pricing efficiency, trust, banking, and ease of use. In our testing, the mobile platform also consistently felt smoother and more polished than competing platforms, especially during active live events when execution speed and market stability matter most.
Market liquidity: ⭐️ 4.7/5
Market variety: ⭐️ 4.9/5
Fees and limits: ⭐️ 5/5
User experience: ⭐️ 5/5
Deposits and withdrawals: ⭐️ 4.9/5
Bonuses and promotions: ⭐️ 4.8/5
Resolution reliability: ⭐️ 5/5

Best for: Regulated prediction market trading and real-money sports contracts. Traders who want fair pricing, straightforward settlement, a native in-app combo builder with same-game capability, and an easy-to-use, reliable mobile trading app.

👍 Why we like it

  • CFTC-regulated U.S. prediction market exchange
  • Excellent liquidity on major sports and the biggest news markets
  • Beginner-friendly interface with advanced trading tools
  • Fast USD deposits and withdrawals
  • Native prediction market 'Combo Builder' for parlay-style prediction markets with same-game capability

📈 Markets

  • 🏈 Sports (NFL, NBA, MLB, NHL, golf, soccer, and futures)
  • 🗳️ Politics & elections
  • 💹 Economics & inflation
  • 🌦️ Weather & climate
  • 💰 Crypto & finance
  • 🌍 Breaking news and world events

🆕 Latest feature

Kalshi Pro gives experienced traders a professional desktop workspace with multiple charts, live order books, customizable layouts, and real-time monitoring of roughly 2,000 markets — bringing a Wall Street-style trading experience to prediction markets.

💳 Pricing & fees

Kalshi keeps its fee structure simple and transparent. Contracts trade between $0.01 and $0.99, with winning positions settling at $1.00. Rather than charging a traditional commission, Kalshi applies a 2% fee on profits, capped at 10% of the contract value, whether you're opening or closing a position before settlement.

🎁 Welcome offer

Use Kalshi promo code SI35 to unlock $35 in bonus credits. All you need to do is deposit $10+ and settle $25 in qualifying trades to unlock the bonus.

🛠️ Room for improvement

While Kalshi offers some of the best prediction markets with excellent liquidity on major sports, we'd like to see a broader selection of player props, entertainment markets, and niche sporting events to better compete with other leading prediction platforms. While their welcome offer does offer the best upside in the industry, a fixed-amount bonus would be a great alternative for more conservative or beginner traders.

2. Polymarket - Best prediction market app for global events

🏆 SI Verdict: ⭐4.8/5
Polymarket stands out for global events because it consistently offers one of the widest ranges of international news, politics, and cultural prediction markets available. In our experience, the platform stands out during major world events when trading activity spikes and traders are looking for fast-moving markets beyond traditional sports coverage.
Market liquidity: ⭐️ 4.8/5
Market variety: ⭐️ 4.9/5
Fees and limits: ⭐️ 4.6/5
User experience: ⭐️ 4.7/5
Deposits and withdrawals: ⭐️ 4.8/5
Bonuses and promotions: ⭐️ 4.9/5
Resolution reliability: ⭐️ 4.8/5

Best for: Sports prediction markets, massive combo payouts, and active mobile traders. The highest amount of overall liquidity on the best prediction markets.

👍 Why we like it

  • Deep liquidity on major sporting events
  • Native 32-leg Combo Builder for parlay-style predictions with same-game capability
  • Broad selection of sports, politics, finance, and world event markets
  • Fast, intuitive mobile trading experience
  • Competitive trading fees on sports markets

📈 Markets

  • 🏈 Sports (NFL, NBA, MLB, NHL, golf, soccer, UFC, tennis, and futures)
  • 💹 Crypto & financial markets
  • 🗳️ Politics & elections
  • 🌎 Breaking news & world events
  • 🎬 Entertainment, culture & technology

🆕 Latest features

  • Polymarket Combos let users combine up to 32 prediction markets into a single high-payout position, including same-game combinations.
  • The Combo Cup awards $50,000 in daily prizes to the highest-performing combo traders, making it one of the biggest ongoing promotions in the prediction market industry.

💳 Fees & pricing

Polymarket uses a dynamic exchange model where contract prices fluctuate based on market demand. Sports markets currently feature a maximum effective trading fee of 0.75% on even-money (50/50) contracts, with the updated fee structure expected to expand across additional categories over time. Deposits and withdrawals are free through most supported banking methods, although payment providers may apply their own charges.

🎁 Welcome offer

Use Polymarket promo code SIBONUS to claim a $20 welcome bonus. Simply deposit $10 or more, complete a qualifying trade, and you'll receive one of the best sign-up offers currently available on a regulated U.S. prediction market app.

🛠️ Room for improvement

Polymarket packs a lot of functionality into its trading interface, but that can make it feel less approachable for first-time prediction market users than Kalshi. We'd like to see a more guided onboarding experience, with clearer explanations of pricing, probabilities, and order types for new traders.

Have a look at our Polymarket promo code page for more information on the platform's latest welcome offer, or view our Polymarket review for a full breakdown.

3. ProphetX - Best prediction market app for parlays

🏆 SI Verdict: ⭐4.7/5
ProphetX stands out for its sportsbook-style trading experience, which combines familiar American odds with the flexibility of prediction markets. Features like no-fee trading parlays, limit orders, and live in-game markets make it one of the most engaging platforms for sports-focused traders, while transparent pricing keeps the experience easy to understand for newcomers and experienced bettors alike.
Market liquidity: ⭐️ 4.5/5
Market variety: ⭐️ 4.7/5
Fees and limits: ⭐️ 4.9/5
User experience:⭐️ 4.8/5
Deposits and withdrawals: ⭐️ 4.6/5
Bonuses and promotions: ⭐️ 4.8/5
Resolution reliability: ⭐️ 4.7/5

 Best for: Sports fans who want a sportsbook-style prediction market with American odds and a familiar parlay-building experience.

👍 Why we like it

  • Built exclusively for sports prediction markets
  • Familiar American odds instead of probabilities
  • Live in-game trading and exchange order book
  • 0% trading fees on profitable parlays
  • Up to 12-leg parlays with sportsbook-style experience that allows for futures parlays

If multi-leg trades are your focus, it's worth comparing ProphetX against the rest of the best prediction market combos before you settle on one platform.

🏈 Sports markets

Unlike most prediction market apps, ProphetX focuses entirely on sports, including:

  • 🏈 NFL & College Football
  • 🏀 NBA & College Basketball
  • ⚾ MLB
  • 🏒 NHL
  • ⚽ Soccer (EPL, Champions League, MLS, World Cup & more)
  • ⛳ PGA Tour golf
  • 🥊 UFC & MMA
  • 🎾 Tennis
  • 🏆 Championship futures and player props

🆕 Latest feature

Super Bowl LXI futures are now available, allowing traders to buy and sell championship positions months before kickoff.

ProphetX also continues to expand its live in-game markets and multi-leg parlay options throughout the season, which now include the ability to place parlays with futures bets.

💳 Fees & pricing

ProphetX operates as a true peer-to-peer sports exchange, using familiar American odds rather than probability-based pricing. Straight wagers incur a simple 2% fee on net profits, while profitable parlays settle with 0% trading fees, making ProphetX one of the most cost-effective platforms for multi-leg sports predictions.

🎁 Welcome offer

Use the ProphetX promo code SICOM to claim a $20 trading bonus. Simply complete your first qualifying $10 trade, and the bonus is automatically credited to your account.

👎 Room for improvement

ProphetX is intentionally built around sports only, so you won't find prediction markets on politics, economics, crypto, or current events as you will on Kalshi or Polymarket. As one of the newest CFTC-regulated exchanges, liquidity on smaller leagues and niche markets also continues to grow.

4. Novig - Best prediction market app for trading rewards

🏆 SI Verdict: ⭐4.6/5
Novig combines a peer-to-peer betting marketplace with one of the most generous rewards programs in the industry. Users can earn cash back, referral bonuses, and other incentives simply by participating on the platform, creating value beyond just winning bets. In our experience, while Novig doesn't offer the liquidity or high-end user experience that other platforms do, the site is growing and is a compelling alternative for those who prioritize both better odds and meaningful rewards.
Market liquidity: ⭐️ 4.5/5
Market variety: ⭐️ 4.6/5
Fees and limits: ⭐️ 4.6/5
User experience:⭐️ 4.6/5
Deposits and withdrawals: ⭐️ 4.7/5
Bonuses and promotions: ⭐️ 4.8/5
Resolution reliability: ⭐️ 4.6/5

Best for: Sports prediction markets, no-vig pricing, and peer-to-peer trading. Novig is ideal for sports fans who want exchange-style pricing and capabilities with commission-free trading.

👍 Why we like it

  • No-vig, peer-to-peer pricing that often beats traditional sportsbook odds, even in low-liquidity markets
  • Sports-first prediction market covering major U.S. and international events
  • Same-game parlays and multi-leg combo builder on eligible markets (2-12 legs) that update slips as you go
  • Fast, intuitive mobile app with live trading and transparent pricing
  • One of the strongest welcome offers in industry for new users

📈 Markets

  • 🏈 Sports (NFL, NBA, MLB, NHL, college sports, golf, soccer, UFC, tennis, WNBA, and futures)

🆕 Latest features

Novig has continued expanding its sports prediction market, adding same-game parlays, multi-leg combos (2-12 legs), and additional player props across major leagues. The platform also supports live trading, allowing users to buy and sell positions throughout games as market prices change.

Novig received CFTC approval as a Designated Contract Market (DCM) in June 2026, completing its pivot toward a federally regulated prediction-market/event-contract model.

💳 Fees & pricing

Novig operates a peer-to-peer prediction market where users trade directly against one another rather than against a sportsbook. The platform is built around no-vig pricing, meaning matched trades are completed without the traditional sportsbook margin, helping traders secure more competitive prices on major sporting events.

🎁 Welcome offer

Use our exclusive Novig promo code SIBONUS to claim the current welcome offer. New users can get a  'Deposit $10 Get $25' bonus when they sign up with our Novig code, making it one of the strongest fixed-amount sign-up promotions available for sports-focused prediction market traders.

🛠️ Room for improvement

Novig remains almost entirely focused on sports, so users looking to trade politics, economics, or other real-world event contracts will find much broader market selection on platforms like Kalshi or Polymarket. We'd also like to see continued expansion of market depth and state availability as the platform grows.

5. OG - Best prediction market app for social integration

🏆 SI Verdict: ⭐4.5/5
We like OG.com for its social integration capabilities, as it does a better job than most prediction platforms at making trading feel interactive and community-driven. Features like live chat and leaderboards add a more engaging layer to the platform, especially during major sports and trending event markets.
Market liquidity: ⭐️ 4.6/5

Resolution reliability: ⭐️ 4.6/5

Best for: Beginner-friendly prediction trading with social features and community competitions

👍 Why we like it

  • Easy-to-use interface for first-time traders
  • Built-in live chat alongside prediction markets
  • Community leaderboards and trading competitions
  • Native 8-leg combo builder with same-game capability
  • Low minimum trade requirements

📈 Markets

OG.com offers a broad selection of prediction markets across major real-world events, including:

  • 🏈 Sports and championship futures
  • 🗳️ Politics & elections
  • 💹 Economics & financial events
  • 🎬 Entertainment & pop culture
  • 🌍 Breaking news & world events

🆕 Latest feature

OG.com's native combo builder now allows users to combine up to eight prediction markets into a single trade, including player props in same-game combo trades.

Integrated chat rooms and live leaderboards also continue to be upgraded, creating a more social trading experience than most competing prediction market apps.

💳 Fees & pricing

OG.com uses a straightforward contract-based pricing model. Users pay a $0.02 fee per $1 traded when opening a position and $0.02 per contract when exiting a trade before settlement. There are no additional fees on contracts held through final settlement, making overall trading costs easy to understand.

🎁 Welcome offer

New customers who sign up with one of our Si-verified OG.com links can claim the OG welcome bonus without a promo code. Simply complete a qualifying $10 trade to receive a $10 trading bonus, making it one of the easiest prediction market promotions to unlock.

🛠️ Room for improvement

OG.com delivers one of the friendliest user experiences in the prediction market space. However, we'd like to see more markets, deeper liquidity, and additional live trading opportunities during major sporting events. It also needs to expand its parlay builder to allow for more than four legs (and to include player props) to make it an even stronger alternative to larger competitors like Kalshi and Polymarket.

New traders can check out our OG promo code page for the latest registration info and information on the welcome offer.

6. Crypto.com - Best prediction market app for crypto users

🏆 SI Verdict: ⭐4.5/5
For traders already comfortable with digital assets, Crypto.com offers one of the most seamless prediction-style trading experiences. The platform stands out for combining crypto funding, trading, and event-based markets into a single ecosystem, making it especially convenient for active crypto users.

Resolution reliability: ⭐️ 4.6/5

Best for: Crypto users who want prediction markets built into an all-in-one digital asset platform.

👍 Why we like it

  • Integrated directly into the Crypto.com app
  • Easy for existing crypto holders to start trading
  • Covers sports, crypto, and major news events
  • No need to use a separate prediction market platform

📈 Markets

  • 🏈 Sports
  • ₿ Crypto price movements
  • 🌎 News and trending global events

💳 Fees & pricing

Crypto.com uses a contract-based pricing model, with trading costs generally built into market pricing rather than charged as separate commissions. Existing Crypto.com users can seamlessly fund prediction markets using their account balances.

🛠️ Room for improvement

While convenient for crypto users, the prediction market experience on Crypto.com isn't as feature-rich as dedicated platforms like Kalshi, Polymarket, or ProphetX. We'd also like to see a broader selection of markets and a simpler onboarding process for users who are new to cryptocurrency.

New users can take a peek at our Crypto.com referral code page for a more in-depth glance at the app.

7. DraftKings Predictions - Best prediction market app for sports traders

What are prediction market apps?

The best prediction market apps let you trade on the outcome of real-world events instead of placing traditional fixed-odds bets. Whether you're predicting the winner of the Super Bowl, the next U.S. election, or an interest rate decision, you buy and sell contracts whose value changes as new information enters the market.

📈 Prediction market apps operate as exchanges, meaning prices are determined by supply and demand rather than a sportsbook setting fixed odds. That also lets you buy, sell, or exit many positions on your phone before an event is officially resolved.

While sports prediction markets have become the biggest draw for many users, leading platforms like Kalshi and Polymarket, and other apps like PredictIt, also offer markets on politics, economics, weather, technology, entertainment, and other major real-world events.

💡 Compared with traditional sportsbooks, prediction market apps typically offer more transparent pricing, the ability to trade positions throughout an event, and access to markets that extend well beyond sports.

How we rate prediction market apps

Choosing a prediction market app isn't as simple as comparing welcome bonuses or counting available markets. Our team tests every prediction market app we review to help readers find safe, legitimate, and easy-to-use mobile trading platforms that deliver a reliable real-money trading experience.

Since prediction markets work differently from traditional sportsbooks, we use a rating system designed specifically for event-trading binary contracts in a peer-to-peer marketplace, not sports betting.

🌊 Market liquidity

Market liquidity measures how easily you can buy or sell contracts without significantly impacting the price. We evaluate order book depth, bid-ask spreads, trading volume, and how efficiently markets perform during both major sporting events and high-profile news cycles.

📊 Market variety

We reward platforms that offer a broad range of prediction markets, including sports, politics, business, crypto, entertainment, and breaking news. We also consider how frequently new markets are added, how clearly contracts are written, and whether pricing remains competitive across categories.

💰 Fees and limits

Prediction market platforms use different fee structures than sportsbooks, so we look beyond headline pricing. Our reviews compare trading commissions, spreads, withdrawal fees, minimum deposits, and position limits to determine each platform's overall value for both casual and active traders.

🧑‍💻 User experience

Every platform is tested on both desktop and mobile. We evaluate account creation, navigation, market discovery, trade execution, portfolio management, charting tools, and overall responsiveness during live trading.

🏦 Deposits and withdrawals

Our team funds accounts using available payment methods wherever possible to evaluate the entire banking experience firsthand. We consider deposit speed, supported payment methods, identity verification, withdrawal processing times, and overall ease of moving money into and out of the platform.

🎁 Bonuses and promotions

Not all prediction market promos offer the same value. We compare welcome bonuses based on bonus size, minimum deposit requirements, trading requirements, promotional terms, and how achievable each offer is for a typical new user.

🤝 Resolution reliability

A prediction market is only as trustworthy as its settlement process. We assess how consistently markets resolve according to published rules, how transparent each platform is about settlement criteria, how quickly winnings are credited, and whether users have access to clear dispute-resolution procedures when needed.

How sports event trading works in prediction markets

The best prediction markets include sports events where you can trade on game outcomes, player performance (player props), and make combo or multi-leg trades. Each possible outcome you purchase in a prediction market is a contract priced between $0.01 and $0.99, reflecting the market’s estimated probability.

How it works

  • You buy or sell outcome contracts in specific markets at a specific price (e.g., Boston Red Sox 73¢”).
  • After you lock in your trade, prices move in real time as new information appears and the outcome resolves.
  • If the outcome settles in your favor (e.g., Red Sox win 4-3), the contract settles at $1 (you'll receive the full profit from your initial trade).
  • You may also settle your trade early, before it resolves, at the current market price (between $0.01 and $0.99).
  • If your prediction is wrong (e.g., Athletics win 4-3), your contracts will settle at $0 and you lose your stake
  • Profit comes from buying low, selling high, or holding to settlement.

How trading on a prediction market differs from sports betting

  • You trade probabilities, not bookmaker odds.
  • You can exit early by selling your position.
  • Prices are set by the market, not the house.

Why do prices move on a prediction market?

  • Injury or lineup news
  • Weather and game conditions
  • Market sentiment and sharp money

The best prediction markets turn sports outcomes into tradable events, rewarding accuracy, timing, and probability awareness rather than fixed bets. The best platforms also combine competitive pricing, strong liquidity, a wide range of markets, and an easy trading experience.

Prediction market apps vs. sportsbooks

Choosing between the best prediction market apps and traditional sportsbooks comes down to how you prefer to wager and what kind of experience you’re looking for. However, for those interested in California sports betting, prediction markets are the only legal option. Bettors interested in Florida sports betting are in a similar situation: you only have one legal option in the state, so prediction markets will offer much more variety than the state's lone betting site, as they allow you to trade on non-sporting outcomes, such as elections. 

You'll also find that users who want access to Texas sports betting or are interested in Georgia sports betting will find prediction market apps such as Kalshi and Polymarket the best legal options for speculating on sports outcomes. 

Prediction market apps vs betting apps. Main differences?

While both prediction market apps and sports betting apps involve predicting outcomes, the ways bets are priced, settled, and regulated differ in important ways.

⚖️ Prediction market apps vs. sportsbooks

Prediction market apps and traditional sportsbooks both allow users to speculate or trade on sporting outcomes, but they operate very differently under the hood. Prediction market apps feature probabilities in their graphics while sportsbooks feature bookie-made odds. 

🏦 Sportsbooks vs. exchange-style markets

Sportsbooks set odds and act as the counterparty to every bet, while prediction market apps function more like exchanges, with prices driven by user demand and contracts settling at a fixed value once the outcome is known.

📜 Regulation differences

From a regulatory standpoint, sportsbooks are governed by state-by-state gaming laws, whereas many prediction market apps fall under financial or commodities regulation, which can limit available markets and alter how risk and payouts work.

🎯 What users should expect

As a result, users should expect simpler, fixed payouts and potentially lower limits on prediction markets, rather than the promotional bonuses, parlays, and high-leverage betting experiences common at sportsbooks.

How to sign up with the best prediction markets

Are prediction market apps legal?

With prediction market platforms and apps like PrizePicks becoming more and more popular ahead of huge sporting events such as the World Series, questions about their legality will continue to dominate discussion. 

We've provided a general breakdown of how you should view the current legal status of prediction market apps in the United States to help makes things clearer.

📜 The legality of prediction market apps in the United States depends on how the platform is structured and regulated. Some platforms, such as Kalshi, operate under federal oversight as regulated event-based exchanges, while others may operate offshore or in legal gray areas that can limit access for U.S. users.

🛡️ Because regulations continue to evolve and enforcement can vary, users should always verify a platform’s legal status in their state and review official terms before participating. This information is provided for general educational purposes only and should not be considered legal advice.

Prediction market apps state guides

Most prediction market platforms are available to eligible users across much of the United States, although availability can vary based on state regulations and platform-specific restrictions.

If you're wondering whether you can use a prediction market app in your state, we've created dedicated guides covering platform availability, legal considerations, and and more for residents of some of the largest states in the country:

How to choose the best prediction market app?

Choosing the best prediction markets can have a big impact on both your experience and your results. While many platforms offer similar contract-based betting, differences in regulation, market depth, fees, and usability can make one app a much better fit than another.

🛒 Market types

Different prediction market apps specialize in different outcomes, such as sports-adjacent events, elections, economic indicators, or pop culture topics. Choosing an app with markets that match what you actually want to trade is more important than sheer market volume.

🏛️ Regulation

Apps like Kalshi operate under U.S. regulatory oversight, while others may be offshore or restricted for certain users. If legality and consumer protections matter to you, prioritize platforms that clearly disclose their regulatory status and compliance.

💲 Fees

Fees can be built into contract pricing, trading spreads, or withdrawal costs, and they vary widely by platform. Lower fees matter most for frequent traders, while casual users may value simplicity over marginal cost savings.

💧 Liquidity

High liquidity means you can enter and exit positions easily without losing value to wide spreads. Apps with more active users and higher trading volume tend to offer fairer pricing and smoother settlement.

Example:

Imagine you want to buy a “Yes” contract on an NBA team winning the championship for $0.62. If there are lots of active buyers and sellers in the market, your trade will usually fill instantly at or near that price. That’s considered strong liquidity.

If liquidity is low, there may not be enough sellers available at $0.62, meaning you could end up paying more than expected or waiting longer for your trade to execute.

📱 UX / mobile experience

A clean interface and reliable mobile app can make a big difference, especially for newer users. The best platforms balance simplicity with enough detail to understand pricing, probabilities, and potential payouts without confusion.
